Rivers suffer from multiple stressors acting simultaneously on their biota, but the consequences are poorly quantified at global scale. We evaluated biological condition of rivers globally, including largest proportion countries Global South published to date. gathered macroinvertebrate- and fish-based assessments 72,275 37,676 sites, respectively, 64 study regions across six continents 45 nations. Because were based differing methods, different systems consolidated into a 3-class system:...
The genus Loboplusia was recently introduced for a remarkable species of Diallactiini from the cloud forest Costa Rica (Jaschhof 2016). Males that species, zurqui Jaschhof, 2016, were found to differ fundamentally other Diallactiini, with following traits defining genus. scutum is provided bright membranous patch called prescutellar window; setae on legs, especially tarsi, are fringed; gonostylus consists two lobes (not single lobe as basic pattern in Diallactiini); and bridge connecting...
The distribution of the longhorned beetle Callipogon (Eoxenus) relictus Semenov, 1899 (Coleoptera: Cerambycidae) in Northeast Asia was summarized for first time, based on examination comprehensive material. is only representative genus Palearctic region. Its ranges from Shanxi province (China) south, northward through Korean Peninsula to Amur Oblast (Russia), and Inner Mongolia west coastal area Russian Far East.
The genus Ephoron Williamson, 1802 is widely distributed around the world. In Thailand, only indicus Pictet, 1843 was reported in 1961. this study, a new mayfly described as ookaewae sp. nov. species description, morphological characteristics of larvae and eggs addition to adults are also shown detail. Number tubercles on mandibular tusks, median frontal process larvae, distinguish from other species. Their polar cap shape concave indentation their unusual. addition, mitochondrial DNA COI...
Abstract Desertification is known to be a major threat biodiversity, yet our understanding of the consequent decline in biodiversity remains insufficient. Here, we predicted climate change-induced range shifts and genetic diversity losses three model dung beetles: Colobopterus erraticus , Cheironitis eumenes Gymnopleurus mopsus distributed across Gobi Desert Mongolian Steppe, areas for desertification. Phylogeographic analyses mitochondrial COI sequences species distribution modeling, based...
The genus Campylomyza Meigen, 1818, belongs to the subfamily Micromyinae (Diptera, Cecidomyiidae). genus, comprising 40 species, is best known in Palearctic Region. To date, four species are recorded Korea: Campylomyzaappendiculata, C.flavipes, C.furva, and C.spinata. Based on our field investigations from 2017 2020, five newly Korea (C.abjecta, C.aborigena, C.cornuta, C.cavitata, C.cingulata) seven new described (C.ambulata sp. nov., C.angusta C.convexa C.cornigera C.hori C.odae C.salicia...
ABSTRACT The tribe Gymnopleurini is a well‐known group within Scarabaeinae, characterized by its diurnal ball rolling behavior. Although mitochondrial genomes have been reported for numerous Scarabaeinae species, those of remain unexplored. In this study, we document the first time genome sequences two ball‐rolling dung beetles, Gymnopleurus mopsus (Pallas, 1781) and geoffroyi (Fuessly, 1775), from infer tribe's position whose phylogenetic relationships largely unresolved. Their are circular...
Abstract Recent molecular analyses of transcriptome data from 94 species across 92 genera North American Plecoptera identified the genus Kathroperla Banks, 1920 as sister group to Chloroperlidae + Perlodidae. Given that has historically been included a member family Chloroperlidae, this discovery indicated further investigation and subfamily Paraperlinae was needed. Both genome sequencing datasets were generated 32 infraorder Systellognatha, including all described Paraperlinae, test...
Abstract In this study, we sequenced both two mitochondrial genes ( COI and 16 S r RNA ) nuclear (28 elongation factor‐1α) from 71 species of O donata that represent 7 superfamilies in 3 suborders. Phylogenetic testing for each concatenated gene sequences based on function (ribosomal vs protein‐coding genes) origin (mitochondrial proved limited resolution. Thus, four were utilized to test the previous phylogenetic hypotheses higher taxa via B ayesian inference BI maximum likelihood ML...
Abstract Diving beetles play an important role in fishless freshwater communities. The genus Cybister is included the Japanese Red Data List owing to its diminished population size. phylogenetic relationships and genetic structures of chinensis brevis, whose populations are declining, tripunctatus lateralis, distribution increasing, poorly understood must be addressed future conservation efforts. In this study, we investigated flight behaviour phylogeography three species. Cybistyer...
The giant water bug, Lethocerus deyrolli, is an endangered wetland insect found throughout East Asia. In 2006, the light-attraction flight of L. deyrolli was studied in Gyodong Island, Korea, using artificial light. observed from early June to late October, and two peaks numbers attracted insects were noted middle September. begins exhibit behaviour at a daily mean air temperature 15°C above, but optimal temperatures for are between 17°C 19°C, with wind speed less than approximately 1.8...
A new species of Ophiuroidea, Ophiacantha scissionis sp. nov., is described. It was collected from Munseom Island, Jeju-do, South Korea at a depth 28-36 m, by SCUBA diving. has unique and distinct morphological characteristics: small disk, densely covered trifid spines, radial shields completely concealed disk six arms with four arm spines proximally, fissiparous. In addition, this clearly distinguished other mitochondrial COI. This usually hexamerous reproduces asexually fissiparity. the...
Abstract DNA barcoding of aquatic macroinvertebrates holds much promise as a tool for taxonomic research and providing baseline reference phylogenetic analysis ecosystem biomonitoring. We obtained 112 novel sequences the barcode region mitochondrial cytochrome c oxidase subunit I gene representing 11 families, 25 genera, 43 species mayfly (Insecta: Ephemeroptera) from South Korea. No shared all can be identified with barcodes possible exception some species. Minimum levels interspecific...
Abstract Outbreaks of Asynapta groverae , an invasive mycophagous gall midge, in South Korea have been repeatedly reported since the first occurrence 2008. This species is a nuisance to residents owing its mass emergence from newly built and furnished apartments. Here, levels genetic diversity, divergence, structure A. populations were investigated understand their ability survive novel locations. Population analyses performed on seven populations, including outbreak, sporadically emerged,...
Most large rivers in South Korea run through major cities, which often experience many environmental problems, including outbreaks of non-biting midges (Diptera: Chironomidae). However, chironomid species inhabiting have not been thoroughly investigated. We aimed to identify collected from the four main Korea, construct a corresponding DNA barcode library, and examine distribution community structure identified riverine species. Adult chironomids were nine sites along by using sweep nets...
The nonbiting midge, Glyptotendipes tokunagai Sasa (Diptera: Chironomidae), is an organism that can be used as a water quality indicator. Development of this insect under different temperatures was evaluated. highest egg hatching rate 99.12 ± 1.47% at 30°C, and the lowest 84.50 11.09% 10°C. No eggs hatched 8 42°C. Developmental (1/h) increased gradually temperature from 10 to 35°C with peak (0.045 0.0079) 35°C. estimated lower thermal threshold for 9.3°C. Adult emergence (80.6%) 30°C (22.2%)...
Abstract We investigated the molecular phylogeny of isonychiid mayflies inhabiting East Palearctic region, Isonychia ( ) japonica , ignota ussurica and Prinoides shima . discuss their genetic structures, phylogeography. collected a total 100 specimens mayfly species from 47 localities Northeast region (the Japanese archipelago, Korean peninsula, Russian Far Mongolia). analyzed DNA sequences at mtDNA COI 16S rRNA regions, nuDNA Histone H3 region. As result our analyses four mayflies,...
Abstract Food‐associated insect pests are of great economic and hygienic importance. However, their identification requires expert knowledge excessive time. Such discovered in food as body parts or immature stages, which further complicates the process. In this study, we constructed a DNA barcode dataset that can be detected food. We also tested efficacy these sequences for identifying food‐associated pests. A 658 bp fragment mitochondrial cytochrome c oxidase subunit I ( COI ) gene was...
